Experts in sand handling
Sensor Control is a reliable expert in automation and foundry sand conditioning. On the GIFA 2011, Sensor Control introduces its very own automatic sand testing systems of the SPC series. The SPC system comes in three different types which adapt to different terms and conditions within a sand plant.
The standard system SPC II is preferably installed at a conveyor belt transfer point between the mixer and the molding line. A miniature turntable continuously extracts small amounts of sand from the flowing sand stream and fills a cylindrical test container (Diameter 50 mm, height: 100 mm). The sand sample will be tested for compatibility and optionally for compression or shear strength, moisture content and temperature. The number of test samples per batch can be adjusted based on customer specifications. Based on the measured values, additions of water and bentonite for the next batch can then be corrected. The system consists of only a small number of moving components thereby guaranteeing long life expectancy with low maintenance requirements.
Here, the standard system SPC II and a sampling and preparation unit is mounted directly on the mixer. The SPC III solution is suitable for all types of mixers with a fixed mixing drum. To mount the equipment requires an opening in the mixer’s drum wall of approximately 70 mm. The sand sample is prepared and then dropped into the cylindrical test container. The same measurements can be taken as for the standard system.
SPC IV consists of the standard system equipped with a mechanical device capable of extracting sand samples directly from the conveyor belt. This mechanical device can be designed in a variety of ways and will be developed with considerations of the customer requirements. This system is also capable of performing the same tests as the standard system.
